Why does one stop sleeping when one becomes old? I'm in bed by 10 every evening but then I'm awake before 5. I mean wide awake, bouncing around the walls awake. Obviously I have to get up for a gypsy's, and then - that's it, I'm up. So I've got 4 hours to kill before work. Sometimes I do a 5k run and then go for a 5 mile walk.

By 10 a.m. I'm shattered

How're your diurnal rhythms working out for you?
